High Chlorinated Polyethylene (HCPE Resin) from China Suppliers and Factory - Durable, Chemical-Resistant Coating

High chlorinated polyethylene resin, produced in China, is a specialized polymer made from polyethylene through a thorough chlorination process. This chlorinated polymer contains 65-69% chlorine and is characterized by its transparency, hardness, and brittleness. Known for its remarkable chemical stability, this resin offers exceptional resistance to salt water and ultraviolet light. It dissolves easily in polar organic solvents such as toluene, xylene, and esters, resulting in a transparent solution that ranges from colorless to pale yellow. The molecular structure lacks double bonds, with chlorine atoms distributed randomly throughout. When applied to surfaces like metal, concrete, or paper, the solvent evaporates at room temperature, leaving behind a transparent, hard, and lustrous glass-like film. This film effectively inhibits moisture and oxygen permeation while demonstrating high resistance to various chemicals, including acids and alkalis. As a corrosion protectant, it also serves decorative purposes, making it a versatile choice from reliable China suppliers and manufacturers.

    Product Introduction

    HCPE resin can be used as gravure printing ink, the binder of heavy-duty anticorrosion paint, waterproof paint and the component of adhesives. Particularly, due to its high corrosive resistance to Cl-, it is especially suitable for being used on vessels, docks, containers coating. The paint made of HCPE can be used in chemical equipment, oil field pipelines, offshore facilities, ship coatings, metallurgy and mine, salt industry, fishing ground, wastes treatment, transportation facilities, container and electrical equipment.

    HCPE has good film forming property, weather resistance, ozone resistance, heat aging resistance, flame retardant, chemical corrosion resistance. It is mainly used for anti-corrosive coatings, fireproof coatings, adhesives and other fields.

    HCPE-101L (Low viscosity) and HCPE-201M (Medium viscosity) are mainly used for anti-corrosive coatings, such as container coating, buried pipeline coating, steel structure anti-corrosive coating and fire retardant coating, road marking paint, etc.

    HCPE-301H (High viscosity) is used for the production of PVC/CPVC adhesive. Such as for hard pipe, pipe fitting, socket, ABS, organic glass and other thermoplastics.
